Fix some test_multiprocessing flakiness.

Potentially introduced by #25845

not joining that thread likely leads to recently observed "environment
changed" logically passing but overall failing tests seen on some
buildbots similar to:

1 test altered the execution environment (env changed):
test.test_multiprocessing_fork.test_processes
2 re-run tests:
test.test_multiprocessing_fork.test_processes
test.test_multiprocessing_forkserver.test_processes

(cherry picked from commit ea1803e)
